Exercise 15 Page 206

Use the Addition Property of Equality to isolate w on the left-hand side of the equation.

w=8.8

Practice makes perfect

To solve the equation, we have to isolate w on one side. Let's use the Addition Property of Equality and add 3.2 to both sides of the equation.

w - 3.2 &= 5.6 w-3.2+3.2 &= 5.6+3.2 w &= Now, let's perform the addition to find the value of y. The sum of 5.6 and 3.2 is 8.8. w - 3.2 &= 5.6 w-3.2+3.2 &= 5.6+3.2 w &= 8.8
